Title: Apparatus for propelling, conveying and mixing gaseous media of different origins by means of a suction fan
Inventor: HINGST RUDOLF
IPC: F24F7/06
Filed: 1957-05-07
Abstract: 833,786. Centrifugal and axial-flow fans. SCHMIDT'SCHE HEISSDAMPFG.m.b.H. May 7, 1957, No. 14465/57. Class 110 (1). [Also in Group II] A suction fan 1, Fig. 3, is arranged to mix two or more gases and discharge them through a common duct 13. As shown, a first gas is drawn into a duct 8 by the fan 1 from inlets 14. A second gas from a trunk 19 enters the duct 8 through hollow fixed blades 18, whilst a third gas is supplied through a duct 15, coaxial with the fan shaft to the hollow hub 3 of the fan, from whence it enters the discharge duct 13 through openings 4 in the hollow fan blades 2. Referring to Fig. 4, the hollow blades 2 communicate with the hollow hub 3 through openings 6 and the leading face 21 of the blade is longer than the trailing face 22. If desired the blade 2 may be provided with a baffle 24, Fig. 5, forming a suction duct 25 connected at 28 with the hub interior 5, and at 27 with a pressure duct 26 connected to the opening or openings 4. The fixed hollow blades 18 and the trunk 19 may be omitted and the fan then used for mixing two gases. Alternatively, the fan as shown in Fig. 3 can be used for mixing only two gases.

Title: Nuclear Reactors
Inventor: BOOTH DAVID LAWRY
IPC: G21C9/012
Filed: 1966-04-01
Abstract: 1,151,334. Reactors. ENGLISH ELECTRIC CO. Ltd. 30 March, 1967 [1 April, 1966], No. 14467/66. Heading G6C. In order to prevent the release of radio-active material for a nuclear reactor in the event of an accident, the radio-active fluids are directed through the water of a refuelling tank so as to effect condensation of the fluids and a reduction of pressure. The heavy-water moderated reactor core is supported in the calandria, 12, beneath the refuelling pond 26, together with the steam drums 20, within the concrete pressure vessel 10. In the event of a fracture of pipe 19, pressure tube 16 or any other section of the reactor coolant circuit, water and steam which are released into space 31, flow through the spaces 28 and pond 26 into the upper space 32. Pressure is thus reduced by condensation in the pond. In addition, pond 26 serves as a radiation shield during refuelling, by machine 33, when plugs 35 are removed.

Abstract: 1,008,374. Self - threading tape - recorder. MINNESOTA MINING & MANUFACTURING CO. April 13, 1962 [April 13, 1961], No. 14488/62. Heading G5R. A relatively stiff leader 77 is attached to the leading end of a magnetic tape 76, stored in a cassette 69 of the type described in Specification 1,008,373 such that in the fully rewound position, the leader is coiled around the outer perimeters of the spool cheeks, where it is engageable by shiftable drive means 53, 242 to push the leader out of the cassette through the channel 78, the natural stiffness of the leader taking it to the position shown in Fig. 4, where a hole 81a in its leading edge is engaged by a pin 90 on the take-up reel. The take-up reel cheeks 81, 82 are spaced to accommodate the width of the leader, which after one turn of the take-up spool, engages the surfaces 118 of a channel-section member 121 extending between cheeks 81, 82. Displacement of the member 121 disengages the drive 53, 242 and engages a plastic member 104, 105, 106 about heads 93, 94, while engaging a pinch-roller 142 with a capstan 41. An end-of-tape foil 216 energizes a solenoid (not shown in Fig. 4) to pull rod 198 to disengage the take-up reel drive, disengage the pinchroller 142 and pads 104-106 and engage a drive to the feed reel at 25. A hold-on contact maintains the solenoid energized until the end of the leader passes a sensor 221, which releases the solenoid and either stops, or in an alternative embodiment, engages repeating means for the tape.

Title: Improvements in dehusking sunflower seeds
IPC: B02B3/08
Filed: 1956-05-11
Abstract: In stripping husks from sunflower seeds, the seeds are divided into groups, each group comprising seeds having sizes between given limits, the seeds being then fed into a dehusking machine which is set so that the shortest distance between the relatively approaching dehusking members of the machine is slightly larger than the average size of the kernels to be stripped of their husk, the said members moving at a relative velocity to each other so that the acceleration or deceleration imported to the seeds causes the husks to fall apart or split without damaging the membrane surrounding each kernel.  The best grouping is when the smallest seed with husk in one group is larger than the largest kernel without a husk in the next group of smaller sized seeds. After the customary winnowing and sieving, the stripped and partially stripped kernels, i.e. those that have been crushed together with their husk or those caught in the opening of their split husk, may be removed by shaking on a stretched cloth held in a slanting position, the kernels with a husk attached travelling further down the cloth.

Abstract: 930,617. Winding and reeling. SCHLOEMANN A.G. April 25, 1961 [May 10, 1960], No. 14874/61. Class 83 (4). Air cooled wire reeling apparatus includes a casing or pit, for a reel basket, having cooling air inlet apertures around the upper portion of its periphery and cooling air outlet apertures underneath the winding space of the casing or pit, the casing or pit having a top cover carried by a device which removes the completed coil, apertures for the passage of cooling air being provided in the base of the reel basket between concentric rings of vertical bolts thereon, and also in the support member, vertically slidable in the reel basket to lift the completed coil therefrom. Wire fed into a casing 6 is laid in loops on a support plate 2, between concentric rings of vertical bolts 1a, 1b carried by a member 3, rotated by a hollow driving shaft 5, and extending through the plate 2. The casing 6 is closed by a cover 28 during reeling. Cooling air from a passage 11 passes through apertures 10 in the upper part of the casing periphery to flow over the coiled wire, through apertures 2a in the support plate 2 and apertures 3a in the member 3 between the rings of bolts 1a, 1b, and out through apertures 12. At the completion of the reeling operation the cover 28 is raised slightly and with discharge means 14 moved to the right as shown in the Figure. The coil support 2 is then raised by a rod 8 to present the coil to the means 14 which then move to the left to remove the coil. The means 14 is supported on bars 13 moved axially by a gear 16. The bars 13 also carry, on arms 23, the cover 28. Wheels 26a, 26b, on spindles in slots in the left and right arms 23, respectively, are adapted to roll the wheel 26a from a position off a rail 29 up on to the start of the rail and the smaller wheel 26b from a position on the rail 29 up a step 29a on to a raised part of the rail 29. This movement serves to lift the cover 28 from the casing 6 and carry it to the right.

The lining is made of elastic material e.g. of foam plastics polyethylene foam, and is preferably a multi-layer construction in which foam web sections of like different density are bonded to one or to both sides of a reinforcing structural layer. The structural layer may be a thermoplastic or thermosetting plastics material such as polyethylene polypropylene or ethylene propylene copolymer, vulcanized fibre board, paper impregnated with phenol or melamin resin, a rigid polyvinyl chloride, expanded metal, metal mesh, resin impregnated glass fibre fleece, or fabric. In another embodiment, Fig. 2, (not shown) two clamping beads 3a, 3b are arranged on the bent-over rim portion. The foam plastics webs can be preheated by flame action, hot air, radiators, resistance heating, or a heating tunnel and bonded with the reinforcing layers using light pressure, or alternatively the bonding can be achieved by adhesives. If a perforated reinforcement layer is provided the foam plastics web can pass through the openings so that a direct bonding can be achieved during foaming.
